| Aug 31, 2016 at 13:33 | comment | added | Tyson | @inf3rno home networking equipment doesn't have grounding connections. Your best route at this point is ignore the shield. Cut it back and skip grounding it. To properly ground it, you need components that don't exist at the home networking level. | |

Nothing will get damaged, stress less. The shielding essentially just shunts noise to earth, it is not going to blow anything up. | |
| Aug 31, 2016 at 13:19 | comment | added | inf3rno | @Tyson Actually it was an accident, I thought it would give me less noise. I still don't get how can I ground it. I have only a combined modem and router at the end of the cable, but not patch panel. On top of that this modem does not have a grounded electric plug. So if shit happens and somehow electricity is induced in the shielding I am afraid it will burn my computers. :S | |
| Aug 31, 2016 at 2:45 | comment | added | Tyson | @inf3rno why did you choose shielded csble? Most home networks use UTP. You ground the shield at the patch panel, not at the end with wall outlet. It true tho most people don't use enterprise grade patch panels at home. | |
| Aug 31, 2016 at 2:42 | comment | added | D-on | The case of the mech is metallic, this is connected to the shield of the cable which goes all the way back to the patch panel, which is metal, through that to the rack which is bonded to a comms earth, which is bonded to electrical earth. If you going to do point to point cabling with insulated housings/outlets you will likely need to investigate alternative ways to earth it. Performance is still better than UTP if not properly earthed as the shield is beneficial. However if there is no reason to use shielded cables and it increases cost and difficulty I would go with UTP in residential. | |

| Aug 31, 2016 at 1:14 | comment | added | inf3rno | I am not sure I fully understand. For example by a keystone module like this: logicit.hu/shop_seopic/2717/Delock_86205/big/… and by a wall outlet like this: logicit.hu/shop_ordered/2717/shop_altpic/big/… the current would go from the shielding through the keystone module and the metal frame of the wall outlet and it would end up in the wall? Or would it stay in the cables because this keystone module is insulated and would flow through the PC, TV or router instead? | |
